motives, (being in part a continuation of my application filed AprilBO, 1909'; Serial No. of which the'following is a vspeci fication. j I H ,My invention relates to electric locomo- In one aspect, the object of my invention is to provide a new and improved spring or yielding drivin connection between a motor armature an a shaft,

In another aspect, the object of my invention is to provides; new and improved system of spring suspension for supporting a and the. cooperating shaft or members. rigidlyQmounted which, ompr ses; a thr ughqs idj the motor armature upon an axle or shaft, while at the-same time providing for a driving connection between the armature and the axle or shaft, V I m a f While I have shown my invention as embodied in atWo-truck locomotive, it will, of

course, be understood" that it may equally well be used in locomotives of other types. ,The above mentioned objects of my invention are carried out bymeans offa yielding the armature axle and the n S af s extending thei driving: connection between i nd s P-PQ ranged, o e tr,

The racks are connected by a leading connectior 13 of. any suitable and well-known form, this connection serving as a bin ed joint between the trucks through whic the tra ctive effort of one truck is transmitted to the other, it being understood that in the particular locomotive shown the draw ha] a are mounted upon .the truck frames. The ruck A is connected to the body frame of tie cab by a pivotal connection 14, ofany w lll-kIlOWILfOl'ID, and the truck B, is connecte [to the frame bya pivotal and longitudinally slidmg connection 15., also of an well-known form.

The frame of the truck B is supported upon its journal boxes through springs 35, links 36 and one equalizing lever 37 arranged as shown. This system of suspen' sion' for the motor frames is described and claimed in a divisional application. I will now proceed to describe the yielding driving connections between the armatures of the motors and the shafts or axles.

Owing to the fact that the torque of single-phase motors is not stead but is con stantly varying from zero to t e maximum, it has been found desirable, where such mo,- tors are used for railway-work, to provide a spring drive between the motors and their cooperating shafts whereby this varying torque is reduced to a-more or less constant torque. My yielding driving connection may be used for this purpose or for a yielding support and driving connection. In Fig. 6, have shown'it merely for a driving connection, while in the other figures of the drawings I have shown it also as a spring support. Although I shave shown my yieldconnection in connection with ingdrivin a shaft having two driving wheels, it may be used in connection with a shaft having two members adapted to cooperate with said connection such as cranks or the like rigidly mounted thereon.

Referring to Figs. 1 to 5, inclusive, .each -of the armatures of the motors, which may be of the usual form for gearless railway motors, is built upon a hub or spider. The armature is shown in dotted lines at 40 in Fig.- 4. This spider is provided with a plurality of circularly arranged holes, through which spring'rods 41 are adapted to pass.-

These'rods ma be of the form shown in Figs; 4 and 5; t at is, they may be larger at portion than at their ends.

e rods 41 are supported in holes in the hubs of the driving wheels,

'these holes, in the particular construction shown, being lined with a bushing 42 of suitable material. such as brass. By forming the ends of the rods 41,-as shown, with a head 43 havin a round surface which snugly fits the ho es in the'bushing 42 and 'by' making the cylindrical portion 44 slightly smallerthan the hole in the bushing 42, bending of the rod 41 is provided for, and when the portion 44 is brought into engagement .with the bushing- 42 the effective length. of the flexible rods between the supporting points is decreased. With such an. arrangement the yielding effect of the rods is decreased after the same have been flexed a certain amount. The assembling of the-wheel axle, wheels, motor armature- -and'spring rods 41 is facilitated by the holes 45 through the crankdisks upon these axles, said holes being located in line with the holes through the wheel hubs and, therefore, permitting the rods 41 to be inserted through the crank disks and wheels into the holes in the spider of the motor armature. The bushings 42 may be firmly held in place by spring washers 46 inserted in grooves near the outer end of the holes through the wheel hubs.

Referring to Fig. 6, it will be noted that the arrangement of the sprin rods 41 in the armature of the motor and in the wheels is like that of Fig. 4. The armature, which is shown in dotted lines at 40', is, however, journaled about the axle or shaft so that it may move slightly around said shaft. this arrangement, the armature is supported on the shaft but is yieldingly connected thereto through the rods 41 and the wheels, which are rigidly mounted on said shaft.

Features of my invention shown and described, but not claimed herein, are claimed in my applications, Serial No. 493,093, filed. April 30, 1909 and Serial No. 590,956, filed Nov. 7, 1910.

What I claim as new and desire to secure by Letters Patent of the United States, is,

-1. In combination, a shaft, a pair of members rigidly mounted on said shaft and having holes concentric with said shaft, a motor for driving said members having an armature surrounding said shaft, and a yielding driving connection between said armature and said-members and shaft comprising flexible rods extending through said armature and having their ends supported in said holes;

2. In combination, a shaft, a pair of members rigidly mounted on said shaft and having holes circularly arranged therein, a mo tor for driving said members having an armature surrounding said shaft, and a yielding driving connection between, said armature and said members and shaft comprising flexible rods extending through said armature and arranged substantially parallel to sald shaft and in a circle concentric therewith, the ends of said rods'being held in said holes.

.3. In an electric vehicle, an axle, a pain of driving wheels rigidly mounted on said axle, a frame in which said axle is journa le d, a motor for driving said wheels comprising a field structure mounted on said frame, an armature surrounding said axle, and a yielding support and driving connection between said armature andsaid wheels and axle comprising flexible rodsextending through said armature and having their ends supported in holes in said wheels concentric with said axle.

4. In an electric vehicle, an axle, a pair of driving wheels rigidly mounted on said axle, a frame in which said axle is journaled, a motor for driving said wheels comprislng' a field structure mounted on said frame, an armature surrounding said in through said armature and having their,

en 5 mounted in holes circularly arranged in-the hubs of saidwheels.

5. In an electric vehicle, anaxle, a pair of driving wheels rigidly mounted on said axle, a frame in which said axle is journaled, a motor for driving said wheels oomrising a field structure mounted on said rame, an armature surrounding said axle, and means for yieldingly supporting said armature for driving said wheels therefrom comprising flexible rods ex ending throu h holes in said armature and arranged stir stantially parallel to said a rle and m a cir- 20 ole concentric therewith, t 1e ends of "said rods bein held in circularl I arrangedholes in said w eels, said holes b in so arranged that the effective length of :aai flexible rQdS' betweenv the supporting oints decreases 5 when said rods are flexed. 1
